Course Description
Geomorphology examines processes that have shaped, and continue to shape, the landscape around us. Resulting landforms and the forces involved are explored using both qualitative and quantitative methods. This course considers issues such as damming rivers, slope stability, and the ongoing interaction between human activity and geomophic processes in the local region. Landforms and processes are analysed at various temporal and spatial scales, and in terms of relevant theories and principles. Field trips investigate the geomorphology of the local area.

Learning Outcomes
At the conclusion of the course, a successful student will be able to:
- Describe the morphology of the landscape and related processes in areas influenced by fluvial, glacial, periglacial, aeolian, coastal, and arid systems.
- Describe major scientific ideas and theories about the development of the landscape.
- Critically analyse geomorphological issues in a scientific context at local, regional and global scales.
- Use topographic maps, aerial photographs, and other quantitative techniques to analyse landforms and processes of land formation.
- Use basic techniques to identify, measure, and analyse landforms and processes of land formation.
